Hi Friends,
I am facing a trivial problem with OpenSSL implementation on Windows platform. To avoid the compilation of source code, I am using the OpenSSL installation for Windows platform, available from shininglightpro.com (http://www.shininglightpro.com/download/Win32OpenSSL-0_9_8g.exe)(Win32 OpenSSL v0.9.8g). I have created a sample server application which initializes the OpenSSL library using API SSL_library_init(). Also I am using the following APIs to load the error string (SSL_load_error_strings, ERR_load_BIO_strings, ERR_load_SSL_strings & OpenSSL_add_all_algorithms). Once this is done, I am opening the certificate file and private key file using APIs SSL_CTX_use_certificate_file & SSL_CTX_use_PrivateKey_file. .The certificate file and private key file PEM (base 64 encoded). In addition to this, I have added the following .lib files in the project setting of VC++ 6.0 (libeay32MD.lib libeay32MDd.lib libeay32MT.lib libeay32MTd.lib ssleay32MD.lib ssleay32MDd.lib ssleay32MT.lib ssleay32MTd.lib) This is working absolutely fine with the sample server application. The same code does not work i.e. opening the certificate files, when I try to execute from a Windows NT Service (Ours is an application running as a service and that service in turn acts as a TCP server which will open SSL ports for communication with client) The same set of APIs and certificates does not work (SSL_CTX_use_certificate_file & SSL_CTX_use_PrivateKey_file) from within a Windows NT service application). Also, when I try to get the latest SSL error numbers using API ERR_print_errors_fp, the entire application crashes. I am looking out for any architectural issues with OpenSSL when working with Windows NT service applications. If anyone has tried implementing OpenSSL in a Windows NT service, any help in this regard is highly appreciated.
